I got Master Windu about a week ago and he has this metalic coloring to him (Hes had it since we got him at our LPS), I think the coloring looks neat but I saw a fish with velvet and Im not wondering if thats what it is.

Hes in a 5g filtered, unheated tank.. Temp 78
Ammonia and whatnot is all clear
He eats like a pig and swims around like crazy
I saw him scratching once against the gravel but he only did it the once but he was all excited that I came in the room so im not sure it was actual scratching. He flares fine as well and his fins are open and looking fine.
